| Abstract | This work investigates on the potential of coconut shell (CS), coir, sugarcane bagasse (SGB) as bio-conductive fillers in epoxy composites. The elemental composition of the fillers was examined using Carbon, Hydrogen, Nitrogen and Sulphur (CHNS) elemental analysis whereas the morphology of the fillers was observed using scanning electron microscope (SEM). Fourier Transform Infrared (FTIR) Spectroscopy Analysis was performed to examine on the chemical structure of the fillers. The performance of the fillers in epoxy composites was evaluated in term of dielectric properties using open-ended coaxial probe technique. CHNS elemental analysis revealed that the fillers contain up to 48.37% of carbon, and presenceof macroporous structure was detected. The polar nature of the fillers was confirmed from FTIR analysis with the presence of hydroxyl (OH) groups. For the dielectric properties measurement, it was found that the fillers increase the dielectric constant (?'), dielectricloss factor (?"), dissipation factor (tan ?) and electrical conductivity (?) of pure epoxy up to 15%, 42%, 32% and 42%, respectively. With enhancement that is < 50%, the performance of raw natural fibres as bio-conductive fillers is considered as not prominent for microwave heating application and activation process is necessary to improve their conductive behaviour. |
